The 24 V AC/DC coil simplifies control wiring — one coil supply works for both AC and DC control signals, common in mixed-voltage panels. The screw-terminal connection is standard for panel wiring up to this current level — no special tooling needed. The 1-pole configuration switches one line; for three-phase loads you'd need three units or a 3-pole variant. It's a zero-crossing switching type typical for resistive loads, minimizing electrical noise. The 24 V AC/DC coil can be driven directly from a PLC digital output or a relay — no separate coil supply conversion needed. The screw terminals accept up to 4 mm² wire, typical for 20 A branch circuits. Keep the load wiring separate from the control wiring to avoid coupling noise into the 24 V line. Packaged dimensions of 105 x 27 x 122 mm — the 27 mm width (roughly 1.5 HP) fits in tight panel layouts alongside other SIRIUS modular components. RoHS compliant since 15-01-24, with a REACH Article 33 notification for Lead (CAS 7439-92-1) above 0.1% w/w. This means the part contains lead in some component (likely the solder joints or internal contacts) — not a restriction for most industrial use, but relevant for end-of-life recycling reporting or if you're shipping to jurisdictions with strict REACH documentation requirements.","metaTitle":"Siemens 3RF3320-1AA14 SIRIUS 3RF33 Solid-State Contactor, 20","metaDescription":"Siemens 3RF3320-1AA14 SIRIUS 3RF33 solid-state contactor, 1-pole, AC-1 20 A at 40 °C, 48-460 V, 24 V AC/DC coil, screw terminals.
